The H-PFQ library depends on certain modifications to the OSKit Linux device driver set (Section 29) that are enabled only when the OSKit is configured with the -enable-hpfq configure option. This configure option enables H-PFQ-specific code in the Linux driver set.
This library will not work correctly with an improperly configured Linux driver set. Similarly, a Linux driver set configured with -enable-hpfq will only work correctly for non-H-PFQ applications if oskit_pfq_root is NULL.
